ABSTRACT

The present invention relates to a container ( 10 ) and a lid ( 14 ), wherein the lid produces audible and tactile feedback when the container is closed with the lid. The invention further relates to a method for forming a lid for engagement with a container. A container with a lid includes at least one thread ( 20 ) on a neck of the container; at least one thread ( 30 ) on the lid; a bump ( 32 ) at the lower part of the lid; an end stop ( 22 ) on a lower end of the neck; and an engagement portion of the neck corresponding to an area where the bump of the lid will engage the neck when the lid is in a fully engaged position. The engagement portion ( 24 ) is arranged such that audible feedback and tactile feedback are produced when the lid moves into a fully engaged position.

FIELD OF THE INVENTION

The present invention relates to a container and a lid, wherein the lidproduces audible and tactile feedback when the container is closed withthe lid. The invention further relates to a method for forming a lid forengagement with a container.

BACKGROUND OF THE INVENTION

Containers with lids which fit together with threads come in manydifferent arrangements, from simply having complementary threads tohaving different closing and/or locking features or arrangements. Someprovide notches, locks, snaps and/or protrusions to secure the containerto the lid. Additionally, these can sometime provide a click or othersound to help the user know when the lid is sufficiently secured to orunsecured from the container.

One such container with lid is shown in in US 2008/0110850 A1. Thiscontainer and lid secure together with threads, and the lid and thecontainer include a complementary notch and lug to provide an audibleindication the lid is sufficiently closed. These notches and lugs arelocated in a central position of the threads, separating the threadsinto segments. Another such container is disclosed in EP 2 080 711 A1,which provides a container for a fabric conditioning composition wherethe lid produces an audible sound by manually forced interengagement ofthe locking members. The closure is stated that it can be a push-onpush-off lid and could include threads with the interengageable lockingmembers, which preferably would be an outward projection on an outersurface of the dispensing opening and a corresponding inwardly orientedrecess on an inner surface of the lid. These can provide audible andtactile feedback to the user.

A number of arrangements are directed toward anti-backoff features forthe lid and container, including GB 2203729 A and WO 2016/016207 A1. GB2203729 A provides a closure system for container which has spaced apartlugs on a neck of a container for engagement by the lugs on the interiorof a skirt of a lid. The lugs on the neck also include a rib whichproject into a space between the lugs of the lid to keep the lid frombacking off. The lugs on the neck include a rectangular slot delineatedby the rib that receive a bar shaped lug on the lid when the lid isfully on the container. WO 2016/016207 A1 provides a closure for acontainer with a screw thread on a neck of the container. At the end ofthe thread, an abutment surface is formed as a stop. A recess or breakis provided in the neck screw thread in which a closure screw threadwith an anti-backoff formation can releasably engage. The anti-backoffformation is a shown and described as a flared thread with a portionwhere the thread segment is thicker vertically in a region forming arectangular flare. While these anti-backoff features would likelyprovide a user with tactile feedback when opening or closing, no mentionof audio feedback is made.

U.S. Pat. No. 4,662,530 relates to a stoppering device with an indexedclosure position, for a bottle made of glass or another rigid substance.

SUMMARY OF THE INVENTION

Nevertheless there is a need for another type of container and lid,wherein the lid produces audible and tactile feedback when the containeris closed with the lid, and which allows a user to easily open and closethe container. The present invention provides such another type ofcontainer and lid.

According to a first aspect of the invention a container with a lidcomprises a container neck surrounding an opening; at least one threadon the neck; at least one thread on the lid for engaging the at leastone thread on the neck; a bump at the lower part of the lid; an end stopon a lower end of the neck which stops further engagement between the atleast one thread on the neck and the at least one thread on the lid; andan engagement portion of the neck corresponding to an area where thebump of the lid will engage the neck when the lid is in a fully engagedposition, the engagement portion comprising a recess adjacent to the endstop for receiving and engaging the bump, and a ramp adjacent to therecess leading into or out of the recess by increasing the outerdiameter of the neck adjacent to the recess, the engagement portionarranged such that audible feedback and tactile feedback are producedwhen the lid is moved into the fully engaged position. The engagementportion further comprises an increase in width of the at least onethread in the neck at the engagement portion. The recess and the bumpeach have a rounded upper portion.

In a second aspect the present invention provides a method of forming alid and a container neck to produce audible and tactile feedback onengagement and disengagement, the method comprising: producing a lidwith at least one thread and a bump at a lower end; and producing a neckwith at least one thread for engaging the at least one thread on thelid, and an engagement portion with a recess for receiving the bump, anend stop delineating the recess and an increase in the at least onethread of the neck and/or the outer diameter of the neck at theengagement portion, wherein the engagement portion and bump are formedto produce specific audible and tactile feedback when the lid is engagedor disengaged from the neck. Each of the recess and the bump have anupper rounded portion.

Such a container with lid is able to secure together and provide a userwith audible and tactile feedback when engaging or disengaging the lidfrom the container. This allows a user to know that full engagement hastaken place. The sensorial feedback also helps the user to ensure fullengagement every time, which is especially useful when container holdsthings are prone to spoilage if not properly sealed between uses, forexample, food products. The engagement of the bump with the recess withend stop also allows for secure engagement and prevent over-torqueingand thereby damaging the container or lid.

The increase in width of the at least one thread in the neck at theengagement portion results in requiring increasing torque for moving thebump through that portion leading up to full engagement. This provides auser with the desired tactile feedback to know when they are reachingfull engagement. The rounded upper portions on the recess and bump canhelp with the movement into and out of the recess, to ensure that themovements are smooth and that the torque required for engagement anddisengagement is not so high that an average user would have problems.

According to an embodiment, the recess extends vertically into theincrease in width of the at least one thread in the neck at theengagement portion. Such a configuration can also produce the desiredaudible feedback when the lid is fully engaged and/or has becomedisengaged.

According to an embodiment, the ramp comprises an increase in the outerdiameter of the neck leading up to the recess, and the engagementportion further comprises an additional ramp which leads from the recessup to the increase in thickness of the neck from the ramp forfacilitating the exit of the bump from the recess for disengaging thelid from the container. This ramp can help to ensure that the forcerequired to disengage the lid from the container is not so great that auser cannot overcome it, and disengage the lid to access the contents ofcontainer. Such ramps can assist in providing tactile feedback to theuser in engaging or disengaging the lid from the neck.

According to an embodiment, the audible and/or tactile feedback isproduced from one or more of: the engagement of the bump into therecess, the stopping of the bump by the end stop, the movement by thebump through the engagement portion, or the movement of the bump into orout of the recess. Depending on the embodiment, one or more of thesework to produce specific audible and/or tactile feedback to the userwhich has been shown to provide reassurance to a user regarding the lidbeing engaged or not from the container. One or more of these mechanismscan work together to form a system which not only produces audible andtactile feedback, but also secure the lid to the container.

According to an embodiment, the audible feedback produced comprises amuffled click of when the lid is disengaging from the container and/or aprecise click when the lid is moved into a fully engaged position. Thesesounds and tactile feedback have been shown to be reassuring for usersas positive indication of fully closed or opened container.Additionally, users link this reassurance to product within thecontainer being fresh and safe from external contamination.

According to an embodiment, the audible feedback has frequency intensityin the range of about 0.00005-0.0036 watt per square meter (W/m²),preferably from about 0.00005 to 0.003 W/m², preferably from about0.0001 to 0.002 W/m². The engagement and disengagement have unique soundprofiles and frequency histograms, respectively, which help the user tofeel and hear the engagement and disengagement process. The soundprofiles and frequency intensity generated upon engagement anddisengagement have been shown to be reassuring for test users.

According to an embodiment, an increase in width of the at least onethread in the neck at the engagement portion and/or the ramp increasestorque required to bring the lid into a fully engaged position.Depending on manufacturing techniques, requirements of the seal, thecontents of the container, etc.; different techniques for producing thetactile feedback related to engagement and disengagement of the lid canbe used. Increasing the width of the thread and/or the neck at theengagement portion can be two such techniques.

According to an embodiment, the sound pressure level of the audiblefeedback generated is in the range of about 20 dB-120 dB, preferably 30to 100 dB, preferably 35 to 80 dB, preferably maximally 70 dB. Thisrange has been found to be reassuring for the test users. The soundlevels referenced for the audible feedback are generally from a distanceof about 0.5 meters, or an arm's length.

According to an embodiment, the audible feedback has a duration of about0.01 seconds or more, preferably, 0.01 to 0.025 seconds, preferably to0.02 seconds. This length of audible feedback has been found to give auser surety that the lid was fully and properly engaged to thecontainer, thereby assuring the user of the freshness of the contents ofthe container.

According to an embodiment, the container with lid further comprises aplurality of bumps and a plurality of engagement portions of the neckfor engagement by the plurality of bumps. A plurality of bumps and aplurality of engagement portions can further secure and produce thespecific desired audible and tactile feedback when engaging anddisengaging lid from the neck.

According to a further aspect of the invention, a method of forming alid and a container neck to produce audible and tactile feedback onengagement and disengagement comprises producing a lid with at least onethread and a bump at a lower end; and producing a neck with at least onethread for engaging the at least one thread on the lid, and anengagement portion with a recess for receiving the bump, an end stopdelineating the recess and an increase in the at least one thread of theneck and/or the outer diameter of the neck at the engagement portion.The engagement portion and bump are formed to produce specific audibleand tactile feedback when the lid is engaged or disengaged from theneck.

Such a lid and container neck include simple features which worktogether to ensure they can be properly and securely engaged and providea user with specific audible and tactile feedback such that the userknows they are engaged or disengaged. The features also help to preventunintentional disengagement and over-torqueing, thereby protecting theseal and/or freshness of anything in the container.

According to an embodiment, the sound pressure level of the audiblefeedback is in the range of about 20 dB to 120 dB.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1A illustrates a perspective view of container 10 with neck 12, andFIG. 1B illustrates a perspective view of lid 14 for engaging containerneck 10. Neck 12 can be formed integral to a container, or can beconnected to a container separately.

Container 10 includes neck 12 with opening 13. Container 10 can be anytype of container, but may be particularly useful for the storage offood products, and especially products which are opened and closed anumber of times during lifetime use.

Neck 12 includes threads 20, end stops 22 and engagement portion 24 withrecess 26, first ramp 28 and second ramp 29. Threads 20 extend around anouter surface of neck 12. In this embodiment, recess 26 is in arectangular shape, and end stops 22 are formed from a generally verticalwall extending beneath threads 20. Ramps 28, 29 are formed by increasingan outer diameter of neck 12 leading up to and coming out of recesses26. This is generally a gradual increase, though the slope and/or lengthcan vary. First ramp 28 can extend about 0.1-3 mm and increase such thatthe outer diameter at high point of ramp 28 is the same as the outerdiameter of neck 12 at threads 20, though it would usually be in a rangeless than threads 30, for example 50% of the height of threads 30.Second ramp 29 is typically much shorter and steeper than first ramp,though it can vary in different embodiments. The length and slope oframps 28, 29 can be used to help produce the specific desired audibleand tactile feedback.

Though container 10 and lid 14 material dimensions can vary in differentembodiments, an example lid 14 and container 10 can be a lid 14comprising polypropylene (PP) and container 10 comprising polyethyleneterephthalate (PET). Container 10 can have a volume of about 600 grams,a neck diameter of about 83 mm and a thickness of at least 0.3 mm. Lid12 can have an external diameter of about 88 mm and a thickness of atleast 1 mm. These dimensions and materials can result in the soundprofiles and frequency histograms shown in FIGS. 2A-2D and 4A-4D.

Lid 14 includes threads 30 and bumps 32. Lid is generally cylindrical inshape on the outer side, and can be formed of a variety of materials.The lid preferably comprises polypropylene or high density polyethylene.Threads 30 extend around an inner surface of lid 14, and bumps 32 arelocated at a lower side of lid, after threads 30 have terminated. Inthis embodiment, bumps 32 are trapezoidal in shape, though otherembodiments could have differently shaped bumps 32 to engage recesses.

Lid 14 rotates to engage neck 12 such that threads 30 on lid 14 engagethreads 20 on neck 12 to secure lid 14 to container 10. Engagementmechanisms are positioned such that bumps 32 must go over ramps 28 andengage recesses 26. Bumps 32 and lid 14 are prevented from furtherengagement (and over torqueing) at that point by end stops 22. Themovement of bumps 32 over ramps 28 provides users with tactile feedback,increasing the torque required for lid 14 engagement as lid 14 comescloser to a fully engaged position. When lid 14 bumps 32 move over ramps28 into recesses 26, audible feedback is produced, for example, in theform of a click.

FIGS. 2A-2D show sound profiles and frequency histograms for thedisengagement or opening (FIGS. 2A, 2B) and engagement or closing (FIGS.2C, 2D) of lid 14 with neck 12. The audible click of engagement betweenlid 14 and neck 12 can be in the sound pressure level range of about 20to 120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferablymaximally 70 dB, and last for more than 0.01 seconds, preferablymaximally 0.025 seconds, preferably maximally 0.02 seconds, as shown inFIG. 2B. As shown in FIG. 2D, the frequency intensity can be in therange of about 0.00005 to 0.0036 watt per square metre (W/m²),preferably from about 0.00005 to 0.003 W/m², preferably from about0.0001 to 0.002 W/m². Lid 13 is stopped from more turning by end stops22, and bumps 32 rest in recesses 26.

To disengage lid 14 from container 10, bumps 32 must be forced up secondramps 29, producing further audible and tactile feedback. The audiblefeedback in this movement is shown in FIGS. 2A and 2D, and can be, forexample, in the form of a muffled click, with similar ranges of 20-120dB, intensity ranges of 0.0001-0.0036 and duration of 0.01 seconds ormore.

As mentioned in the background, some prior art lids and containers haveengagement features in the form of notches and lugs or interengaginglocking members which can provide audible and/or tactile feedback. Thecurrent invention, however, uses a combination of specific features onthe lid and the neck, including a bump at a lower end of the lid, arecess on the neck, an end stop and a ramp which work together toproduce specific audible and tactile feedback which assures a user ofproper engagement or disengagement. These features also work together tosecure the lid 14 to the container 10 and prevent overturning. As in theembodiment shown, additional ramps and/or thickening of threads or theneck can also be used to contribute to the specific audible and/ortactile feedback desired.

The use of engagement features on lid 14 and on neck 12 work togethersecure lid 14 to neck 12 and provide audible and tactile feedback to auser. Bumps 32 provide sensorial feedback when moving over ramps 28, 29into or out of recess 26. The specific audible range produced, theduration and frequency intensity ranges have been found to demonstrateunique sound profiles and frequency histograms. These specific uniquesound profiles and frequency histograms have been shown to help a userknow when lid 14 has been engaged or disengaged and therefore feelassured of the freshness of the contents of the container.

The sensorial feedback, including audible and tactile, helps a user toknow that lid 14 is properly engaged with container 10, thereby ensuringactual sealing of container 10 and freshness of contents inside.Additionally, ramp 28 leading up to recess 26 can help a user feel whenlid 14 is approaching full engagement with container 10, and thesettling into recess 26 provides the user specific feedback that the lid14 is fully engaged. These features also provide the user audible andtactile feedback for the disengagement of lid 14 from container 10,thereby ensuring a user knows that the container 10 and lid 14 werefully engaged and protecting the freshness of the contents of container10 between uses. The sloping sides of trapezoidal bumps 32 (and ramps28, 29) can help to allow bumps 32 into and out of recess 26 without toomuch effort by a user, ensuring that even weaker users are able toengage and disengage lid 14 with container 10 neck 12. Recesses 26 withend stops 22 also help to minimize play between lid 14 and container 10when fully engaged, thereby helping to prevent any loosening or backingoff of lid 14 from neck 12.

FIG. 3A illustrates a perspective view of a second embodiment of acontainer neck 12, and FIG. 3B illustrates a perspective view of a lid14 for engaging container neck 12. Similar parts are labelled similarlyto FIGS. 1A-1B. FIG. 4A shows a sound profile and FIG. 4C shows afrequency histogram of the disengagement (opening) of lid 14 from neck12. FIG. 4B shows a sound profile and FIG. 4D shows a frequencyhistogram of the engagement (closing) of lid 14 with neck 12.

Neck 12 includes threads 20, end stop 22 and engagement portion 24 withrecess 26, ramp 29 and widened thread 34. Threads 20 extend around anouter surface of neck 12, and increase in width in engagement arealeading to recess 26. In this embodiment, recess 26 has a rounded upperportion, which extends into the widened thread 34, and end stops 22 areformed from a wall extending beneath threads 20 delineating recess 26.Ramp 29 is formed by increasing an outer diameter of neck 12 coming outof recesses 26. Ramp 29 is typically quite short and steep, though canvary in different embodiments, and some embodiments may not include ramp29.

Lid 14 includes threads 30 and bumps 32. Threads 30 extend around aninner surface of lid 14, and bumps 32 are located at a lower end of lid,after threads 30 have terminated. In this embodiment, bumps 32 have arounded upper portion to correspond to the shape of recess 26, thoughother embodiments could have differently shaped bumps 32 (and recesses26) for engagement.

Lid 14 engages neck 12 much the same way as the embodiment shown inFIGS. 1A-1B, twisting around neck 12 so that threads 30 engage threads20. When approaching a fully engaged position, additional torque isrequired due to widened threads 34. When bump 32 engages recess 26,audible feedback is produced, for example, a precise click. This can bein the sound pressure level range of about 20 to 120 dB, preferably 30to 100 dB, preferably 35 to 80 dB, preferably maximally 70 dB, withfrequency intensity of about 0.00005 to 0.0036 watt per square metre(W/m²), preferably from about 0.00005 to 0.003 W/m², preferably fromabout 0.0001 to 0.002 W/m², and a duration of about 0.01 seconds ormore, for example 0.01 seconds to about 0.025 seconds, or to about 0.02seconds (see FIGS. 4B, 4D). These specific ranges have been found to bereassuring for the users.

When disengaging lid 14 from neck 12, ramp 29 and/or the shape of bump32 can help to smooth disengagement of bump 32 with recess 26 andre-engagement of bump 32 with threads 20. Audible and tactile feedbackare produced through the disengagement or opening, and can be, forexample, a muffled click produced when bump 32 moves out of recess. Thiscan be at least partially from the deflection of bump 32 and/or lid 14in the movement. The audible feedback can be in the range of about 20 to120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferablymaximally 70 dB, with a duration of about 0.01 seconds or more,preferably maximally 0.025 seconds, preferably maximally 0.02 secondsand frequency intensity of about 0.00005 to 0.0036 watt per square metre(W/m²), preferably from about 0.00005 to 0.002 W/m², preferably fromabout 0.0001 to 0.001 W/m² (See FIGS. 4A, 4C).

By using a bump 32 at the lower end of lid 14 to engage with acomplementary shaped recess 26 and widened threads 34 leading up torecess 26, lid 14 and neck 12 are able to provide specific audible andtactile feedback for a user. The widened threads 34 require additionaltorque to move bump 32 through, and the movement of bump 32 beyondwidened threads 34 into recess 26 produces an audible sound. The torquerange can be, for example, 0.5 to 8 N.m. End stop 22 and widened threadportion 34 help to secure bump 32 into recess 26, thereby helping tosecure lid 14 to neck 12 and prevent any backing off. The shapes ofrecess 26, bump 32 and engagement portion leading to recess 26 all worktogether to produce the specific desired audible and tactile feedbackfor a user as well as to allow a user to be able to engage and disengagelid 14 from neck 12 without too much strain. End stop 22 helps toprevent over torqueing, and therefore damaging the seal which can beproduced between proper engagement of lid 14 with neck 12.

In summary, by providing at least one bump at a lower part of lid 14which can interact with engagement features (including a recess 26 andan end stop 22) on neck 12 of a container, container 10 and lid 14 canprovide a secure connection and specific audible and tactile feedback toa user to indicate full engagement. This can help a user feel moresecure about the freshness of the product inside the container 10 whenthey receive this specific audible and tactile feedback upondisengagement, as well as ensure that the user properly engages lid 14with neck 12 after each use by twisting until the audible and tactilefeedback is produced. This sensorial feedback produced is of such aduration and/or frequency intensity range that an average user feelsreassurance that the lid is properly closed & the container will keepthe product safe from external contamination.

These features can be especially useful for containers 10 which will bestored and/or transported, thereby ensuring freshness of any product incontainer 10.

While neck 12 and lid 14 have been shown with a number of threads 20, 30and a number of engagement features (bumps 32, recesses 26, etc.), thesenumbers and placements are for example purposes only and could bedifferent in different embodiments. Neck 12 and lid 14 much have atleast one bump 32 to engage a recess 26 with an end stop 22, providingaudible and tactile feedback through engagement. Similarly, thedescription and ranges for length, intensity and frequency of theaudible feedback of full engagement is for example purposes only, andthe ranges can vary depending on materials used, thickness of annularengagement features, profile/design of engagement features, materialdistribution, contents of container 10, configuration of neck 14 and lid12, etc. However, the given ranges have been shown to be particularlyuseful to a wide range of users in providing a desired audible andtactile feedback without being overwhelming to a user.

Some specific examples of containers 10 and lids 14 which could be usedto produce desired audible and tactile feedback for a user includecontainers 10 made of PET and lids 14 formed of PP with the followingdimensions:
